Kubernetes on nixOS using k3s (Part 1)
Kubernetes on nixOS using k3s (Part 1)
k3s is a lightweight kubernetes distribution and works incredibly well. It packages all its dependencies, runs using sqlite in place of etcd (although it can use a number of backends!), and has a much lower memory footprint. Building the k3s binary from scratch is quite confusing, but since its a static binary, we don’t have to worry about this. We can simply fetch the built binary from github and run it.

Taking it home — Kubernetes on bare-metal
Taking it home — Kubernetes on bare-metal
To learn how Kubernetes works you should run your own Kubernetes cluster on bare-metal hardware. Discuss this post In the world that I live in Kubernetes is all the rage. This is the world of professional software development and deployment where medium- and large-sized companies are trying to reduce cost and complexity of their IT platforms while at the same time becoming faster at making changes to the software that they run as services to either their internal or external customers.

Issuing and using SSH Certificates | Carlos Becker
Issuing and using SSH Certificates | Carlos Becker
SSH certificates allow system administrators to SSH into machines without having to manage authorized keys in the servers. In summary, you create a key pair to be used as a Certificate Authority (CA), and add the public key of that key pair to the server: TrustedUserCAKeys /etc/ssh/my-root-ca.pub Then, usually, a system administrator or an automated system creates certificates for the users that need to access the servers. Those certificates are created with the CA’s private key, the user’s public key, a list of principals and a validity period.
